[Antennaware] 2 element tribanders

The key word is "advertised."  The height above ground is the principal 
determinant of take-off angle, for any horizontal antenna from a dipole 
on up.  On the other hand, if your house were at the top of a fairly 
steep hill, then your take-off angle could be radically lower.  I very 
much doubt that you could notice a difference among these antennas in 
real life.

The 2 elements ones I have seen on the market with a manageable boom length (6 feet or so) for me include the Mosley TA32jr, Mini 32, and Mini 33, the Cushcraft MA5B, and the Hy-Gain TH2.  In looking at the specs of these antennas there seems to be some real differences in the advertised gain, in the order or 2 or more DB difference on some bands.  Has anyone modeled these antennas at a low height (or used one at a low height) and could comment on their performance or modeled gain?
